I used to have zebra danio's along with sissortail tetras. They all seemd to like swimming mid to upper tank. I moved the zebras, and now the sissortails don't seem as active as they were before. I'm wondering if any of you may know of types of fish that enjoy swimming mid to upper tank? Thanks for reading. Btw, I have a 29 gallon tank.
